The gyro type should be piezo-integral. This setting varies for each model loaded, so check yours.

If you have transmitter controlling the mix, then make sure that the gyro gain channel is assigned correctly and going the right direction, because one way (positive or negative) is HH the other is rate mode, just like the real thing.

If you do not have your transmitter controlling the mix, then make sure that you have the gyro sensitivity specified in the dialog.

Most likely cause is either model is not setup to HH (piezo-integral in F5 window) or your gyro setting/calibration was done improperly. Make sure that if you're using a variable gyro channel that it is set to 0 during center calibration. Also make sure that the proper direction (plus/minus) is correct in channel assignment.
